				        	Objective To establish a method for determining five isoquinoline alkaloids (including berberine,jatrorrhizine,jatrorrhizind,coptisine and palmatine) in Erhuang Xiaoyan tablets simultaneously.Methods Determination by reversed phase high performance liquid chromatography (RP-HPLC).Column:YMC-Pack ODS-AM (4.6 mm× 250.0 mm,5 μm);mobile phase:elution with 0.1% (v/v) formic acid aqueous solution-acetonitrile mobile phase gradient;flow rate:0.4 mL/min;injection volume:10 μL;detection wavelength:345 nm;column temperature:27 ℃.Results Five of isoquinoline alkaloids in Erhuang Xiaoyan tablets were separated perfectly.The good linear relationships were obtained in the following ranges,1.526 4-5.342 4μg (r=0.999 9) for berberine,0.403 2-1.411 2 μg (r=0.999 6) for palmatine,0.309 7-1.083 9 μg (r=0.999 8) for coptisine,0.111 2-0.389 2 μg (r=0.999 8) for jatrorrhizine and 0.162 2-0.567 7 μg (r=0.999 6) for epiberberine.The recoveries were 98.69%,98.66%,98.67%,98.67% and 98.67%,respectively.Conclusion The method possesses high feasibility,strong specificity,high accuracy and good reproducibility,which can be used for the quality control of Erhuang Xiaoyan tablets.
